You need a mac with osx leopard, Setup a developer account at developer.apple.com then download the developer sdk and install xcode. There are very good tutorials in apple's developer section. When you install the developer software on the mac there are more help videos and tutorials in xcode. If you want to publish the app to a "developer phone or ipod touch" or the app store you need to pay $99 . XCODE has a virtual app you can test on so you don't need to pay the $99 yet

"The version of iPhone OS on “iPhone” does not match any of the versions of iPhone OS supported for development with this copy of Xcode. Please restore the device to a version of the OS listed below. If necessary, the latest version of Xcode is available here."

Did you ever solve your problem? I'd love to know how you did it! Thanks

you must have downloaded a new version of xcode. You may need to update your iphone software to 3.1.2 plug the phone into itunes and do an update. I did not update mine cause I run a jailbroken phone and don't know if they jailbroke 3.1.2 yet

Sergio, my professor has put together some very good beginner Iphone programming (objective c) resources. He has his own slides, but he also links to other resources that he considers useful. If you are interested, you can do the projects there also, they follow the slides, so they are all do-able although they are all more difficult than they look. They start out by teaching the basics and fundamental objective c classes and then branch out into things like OpenGL for the Iphone, Core graphics & animations, etc. I've done all of the projects there so if you go that route and need help or examples for something, you can always post in this forum and PM me.
